MACHINE FOR SHAPING POST-AUGER BLADES.

EIPECIPICATION forming part of Letters Patent No. 326,399, datedSeptember 15, 1885.

Application filed June 8, 1895. (Modtl) To aZZ whom it may concern;

Be it known thatI, CLEMENT L. CARTER, of Union City, of the county ofRandolph and State of Indiana, have invented certain new and usefulImprovements in Presses and Dies for Shaping Post-Auger Blades, where itis desired to economize space, and utilize power where heavy pressure isneeded, either by hand or power; and I do hereby declare that thefollowing is a full, clear, and exact description of my invention, whichwill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, which.form a part of this specification, and in which-- Figure l is aperspective view of my invention when used as ahand-power. Fig; 2 is anend view of the same with the convex die elevated and the concave diedrawn out to re ceive the auger-blade; and Fig. 3 is a view of apost-auger blade as taken from the press in perfect shape.

Similar letters of reference indicate corresponding parts in eachfigure.

The object of my invention is to construct a cheap and efficientmachine, with dies to match each other, for forming blades for my patentpost-hole digger, patented June 5 and August 28, 1883, one of the diesbeing concave and the other'convex, to match with lever attachments soarranged that the dies can be brought together with great force, thereby giving the post-auger blade, placed between them, the proper shape,as hereinafter more fully described and claimed.

In the accompanying drawings, R R indi cate the frame on legs to supportthe working parts of my invention; D D, the frame or guides for theconvex die B; O, the concave die; I, the shaft rigidly connected to thedie B.

O is a strong shaft, passing through to the opposite side of the guidesD D, forming a connection with the shaft I on the opposite side by meansof a connectingrod, (not shown in the drawings) to correspond with theconnecting-rod J. (Shown in Figs. 1 and 2.)

F is the lever for moving the concave die, as desired, for conveniencein putting the postauger blade in or removing it.

H is a lever, by means of which the convex auger blades in such a shapethat the augerblades formed by them are straight through the center fromend to end, and have a varying are from the upper to the lower end. Inmy post-hole digger referred to above the blades converge; hence thereason for the varying are.

To explain more fully my invention as seen at Fig. 2, the convex die Bis elevated, the concave die G being drawn out to receive the post-augerblade. The post auger blade being placed on the concave die 0 in properpo sition, is, by means of the lever F and the connection M, broughtimmediatelyunder the convex die B.

It will be seen that the connectingrods J, j

nection at T to the opposite or lower side of j the shaft 0, therebyshortening the distance between the shafts O and I. The lever H beingthe long arm of the lever, the attachment at T the short arm, the shaft0 the fulcrum, it will be seen that when the short arm T passes belowthe center of the shaft 0 its length diminishes as it approaches theline of the center of the shafts I and 0, thereby giving increasingpower.

Having thus described my invention, I claim as new and desire to secureby Letters Patent of the United States The combination of the dies B andO, the guides D D, the levers H and F, the connecting-rods J, theattachment T, and the shafts I and 0, all as and for the purposes setforth.

CLEMENT L. CARTER.
